Amazing watch at its price point!
Very happy about my M50 black ion purchase, it's truly an amazing watch - the value is hard to beat, if not impossible! Nice heft/weight without feeling like a wrist-brick, good legibility to the numerals and face, very pleasing overall. Nitpicks - my wrist diameter is nearly 8 inches so the included NATO strap was too short, I had to use the factory NATO strap on the next-to-last setting, so I removed that original strap and installed a Barton canvas long-length strap and that is perfect. Also, the M50 black ion face is a bit plain - I would love the Momentum logo just under the 12 o'clock marker and all the other text below the logo. Rock that logo, Momentum! If it's as tough as it seems and the battery lasts almost 10 years, then I'd probably give it 6 out of 5 stars. Keep up the good work, Momentum.

SUPERB
I have owned this M50 Ion plated for many months now. Works flawlessly as expected. I also have on original M50 in stainless. This new M50 is a definite improvement over the older ones. It has 120 click bezel, and the lume is absolutely excellent. Lasts all night. I really like the all black Bezel much better than the stainless style. It is quite tough. Had a few bumps and scrapes on the watch. Used a pencil eraser to rub the marks off. looking like new again. You cant go wrong with this watch. This is the watch I wear camping and for all outdoor activity. I don't dive anymore but I never have to worry about it being water proof. This has a real 500 Meter dive rating. A tough as nails watch for a Bargain Price. Keep up the good work Momentum.
